Building muffs for comparison

[zeropluszero]

I've ordered a Double Muff with my last PCB order, and was thinking of breadboarding the muffin fuzz variants before committing.
I was hoping to get another set of eyes over a few parts lists to add to the existing options, I've made some educated guesses with some of them but am open to correction.

Check Kit Rae’s Big Muff page it’ll tell you every version along with different takes such as the Skreddy P19, Cornish P2, etc

Before soldering the 50k resistors over pot-legs 1&3, use some alligator clips to audition the resistors and see if you even want/need them.


On one hand, it makes most sense to choose two very different circuits for the Double Muff, but the PCB could also be used for two subtle variants.

I've been toying with the idea of breaking out the Dual-Gangs to single gangs and making the channel switch a stomper. Then I can have two Identical/near-identical Muffs but set up very differently from each other, say for example one set to low-gain and bright tone while the other is bombastic bassy fuzz. Of course, it'd be fun to have two vastly different circuits, and still do the break-out pots and stomper-channel-switching idea, too.

So many options... such a great PCB idea.
